Definitions

  • the invention relates to a device for fastening cable trays or cable trays to a building wall or ceiling, wherein adjoining cable trays or trays are supported on cantilevers which are attached to the building wall or ceiling at intervals from one another and extend transversely to the longitudinal direction from their attachment-side end the cable trays or trays.
  • the brackets are attached to the wall, while in the case of ceiling mounting, a so-called stick hangs vertically from the ceiling, to which one or optionally several brackets arranged one above the other are attached (e.g. DE-A-1 515 670).
  • cables are laid in the cable troughs or trays within buildings, particularly in industrial plants, whereby according to the dimensioning, a plurality of cables can be placed next to one another in the cable trays or trays mounted in a row, so that these including the cables a fairly large weight to hold on the wall or ceiling.
  • the present invention therefore set itself the goal of avoiding in the manner described above for the creation of a device of the type mentioned above for the highest safety requirements in terms of material and difficult work and the problem of mastering the forces to be absorbed on the boom under extreme situations, in particular to solve the moment forces caused by the forces in the longitudinal direction in a different way.
  • the boom and the axial force strut preferably form an angle of 45 °.
  • the end of the axial force strut which is subjected to tension or pressure, is fastened to the longitudinal center of the cable trough by means of a screw connection.
  • the axial force strut is expediently fastened on the underside to the two spars by means of a screw connection.
  • a cable trough 1 is held on two brackets 2 spaced apart from one another for fastening to a wall, each of which consists of a U-profile carrier with a web tapering towards the free end and a mounting plate welded onto the wider end, which to be attached to a wall by means of screws 3.
  • the cable trough 1 is shown partially cut away in the area of the front bracket 2 in FIG. 1, so that the axial force strut 4 including an angle of approximately 45 ° can be seen below the cable trough in a plane parallel to the bracket and to the bracket.
  • an axial force strut 4 is connected to a bracket 2 in the manner described for each cable tray.
  • the cable tray is held with the possibility of movement in the longitudinal direction.
  • a specially designed bar 7 is riveted to the underside of the cable tray , which is shown in Figs. 4 and 5 on a larger scale.
  • This bar 7 is fastened to the underside of the cable trough 1 with fastening means, preferably three rivets 8.
  • the cable trough is omitted in the plan view according to FIG. 4 and is only partially indicated with dash-dotted lines in order to show how the strip 7 interacts with the bracket 2.
  • the strip 7 is cranked over a partial length and thus has an edge 9 which extends at a distance parallel to the underside of the cable trough and which engages under the upper leg of the arm 2 which is designed as a U-profile, so that this arm of the arm extends between the edge 9 the bar and the bottom of the cable tray. This ensures the transmission of vertical forces or prevents the cable tray from lifting off the bracket.
  • the bar 7 is also over a further partial length 10 at the end of the The bar is flat and engages with this section in a precisely fitting manner in the upper leg of the boom 2 which is notched in accordance with this partial length, so that the horizontal transverse forces are transmitted from the cable tray to the boom at this point.
  • the other end of the axial force strut 4 is connected in the same way as in the cable trough according to FIG. 1 by means of a screw 6 to the bracket 2.
  • the bar 7 for the transmission of the transverse and vertical forces is in principle designed in accordance with the bar described in connection with the cable tray. Since the attachment is only possible on the two spars of the cable ladder, correspondingly short strips 7 can be attached to each of the spars.
  • a cable trough 1 is connected to a subsequent, similarly designed cable trough with the aid of elements 30 bridging the dilatation joint between the cable troughs, wherein in the illustrated case each cable trough rests only on a bracket 2 which is arranged close to a dilatation joint is.
  • an axial force strut 4 is fastened in the same way as in the example shown in FIG. 1 with one screw connection 5 to the cable tray on its longitudinal center and with the other end using a screw connection 6 on the fastening-side end of the bracket 2 attached.
  • FIG. 1 it is shown that a cable trough 1 is connected to a subsequent, similarly designed cable trough with the aid of elements 30 bridging the dilatation joint between the cable troughs, wherein in the illustrated case each cable trough rests only on a bracket 2 which is arranged close to a dilatation joint is.
  • an axial force strut 4 is fastened in the same way as in the example shown in FIG. 1 with one screw connection 5
  • the brackets 2 are each fastened to a ceiling support 31, which are intended for attachment to a building ceiling, so that a plurality of cable ducts can be arranged one above the other in layers on the ceiling supports hanging from the building ceiling.
  • the arm 2, which is designed as a U-profile is screwed laterally with its web to the ceiling support 31 by means of screws 3.
  • the bar 7 is also used in the same version.
